NSTALLED
:
If the unit has been placed in the HI / LOW mode, the unit will be taken to a low or idle setting when the
thermostat is not calling for heat. When the thermostat calls for heat, the unit will go to the setting that
is displayed on the control board Heat Indicator. If the heating load is not great enough when the stove
is on low, the high limit switch will turn the stove off and the switch will have to be manually reset. To
reset the high limit switch, remove the right cabinet side. The switch is found behind the control panel.
Avoid setting off the high limit switch.

NOTE: Fresh air is mandatory on all units installed in “Mobile
Homes” as well as in “Air Tight” homes.
When connecting to an outside fresh-air source, do not use plastic,
combustible pipe. Only 2” (5 cm) ID steel, aluminum or copper pipe
should be used. It is recommended, when you are installing a fresh-air
system, to keep the number of bends in the pipe to a minimum.
Figure 22
This control board can be placed into two different
modes: When the jumper J9 is not jumped
then the control board is in a HI / LOW mode
operation. If the control board is placed with J9
jumped then the control board is in a ON / OFF
mode of operation. In the ON /OFF thermostat
mode, the unit will shut OFF when the thermostat
is not calling for heat. When the thermostat calls
for heat, the unit will go through an ignition
sequence once again and relight.
1. Install the wall thermostat in a location that
is not to close too the unit but will effectively
heat the desired area.
2. Install a 12 or 24 Volt Thermostat using an 18 x
2 gauge wire from the unit to the thermostat.
